The pyroCB cloud exhibited cloud-top 10.3 \u00b5m infrared brightness temperatures as cold as -56.13\u00baC.<\/p>\n In GOES-18 True Color RGB images from the CSPP GeoSphere<\/strong><\/a> site (below)<\/strong><\/em>, shades of tan to light brown helped to identify the smoke-laden anvil of the pyroCb as it drifted northward.<\/p>\n
